News repertoires, civic engagement and political participation among young adults in Israel

AbstractThis study investigates the cross-media repertoires of news consumption of young adults in today’s fragmented multi-media environment, and examines the interactions between those repertoires and the consumers’ civic engagement and political participation. By using a Q-sort method, the respondents were asked to sort a number of elicitation cards on a relational scalar grid, which allowed for subsequent statistical factor analysis of these qualitative data and the generation of a sub-typology of media consumption repertoires as well as the discursive practices of the respondents. We also used a questionnaire which included questions about news consumption, political participation, and civic engagement. The findings revealed that most young adults used repertoires of digital and new media news consumption. The interviewees were highly conscious of their choices of news sources, and some young adults explicitly stated that they preferred to consume news from sources which reflected their own political views. In this study we were able to map news media repertoires of young adults in Israel and found that young adults do participate, and are largely involved, in activism and protests.

Weighted Entropy Coding and Fractional Rate–Distortion Trade-Off for HEVC Encoder with Emphasis on Global Bit Rate

The existence of the mass collection of the videos in the multimedia environment has provided endless service to the users such that the service offered should be of high quality and with low bit rates. With this concept in mind, video compression comes into existence that compresses the video by sustaining the original quality of the video. The proposed FWE-HEVC method introduces a new video compression strategy such that the quality is not degraded and in addition, it offers a higher degree of compression. The paper proposes weight entropy coding for video encoding and a new Rate–Distortion trade-off, named as the Fractional Rate–Distortion trade-off, for the motion estimation. The benefits of the fractional theory are inhibited in this paper. The proposed FWE-HEVC method reduces the bit rates to the half thus, promoting to the reduction in the dimensional area. The experimentation is performed using six videos taken from CIPR SIF Sequences and the proposed video compression method is analyzedin terms of the SSIM that proves that the quality of the video is sustained even after the compression. Moreover, the compression quality is reported as 86.7163% for single video and 83.6772% for multiple videos.

English as a foreign language writers’ metacognitive strategy knowledge of writing and their writing performance in multimedia environments

Writing is a complex, recursive, and strategic process that requires metacognitive competencies. Skillful writers have a high level of metacognitive strategy knowledge (MSK) and use strategies effectively. MSK about writing describes a person’s verbalizable knowledge and awareness of memory, comprehension, and higher order processes that underlie skillful writing. Measurement instruments assessing students’ MSK about academic writing in higher education that can be used for group settings and large samples are lacking. The aim of this article is to describe the development of a new MSK test instrument. The MSK test consists of three different writing scenarios related to the three self-regulated writing phases: planning prior to composing full text, monitoring the writing during composition, and subsequent revision. The findings of a pre-study (N = 51) and two studies (N = 23; N = 113) showed that the new MSK test is economical in use, is reliable and has high content validity. Further, the findings demonstrated external validity of the new instrument in terms of relationships with students’ metacognitive strategy use and writing performance. Implications for future research and educational practice are discussed.

The Creation of Maze in Order to Hide Data, and the Proposal of Method Based on AES Data Encryption Algorithm

The field of science, which enables the transmission of private data in multimedia environments such as display, audio and video, is called steganography. The widespread use of the internet in our daily lives has brought about the problem of transmitting confidential information. Hence, the need for steganography science has also increased. In this study, a labyrinth is produced in the size of the environment in which the data can hide with the help of a private key. Color images with 24-bit depth were used as data hiding environment in different measures and different formats. For the production of maze, the Depth First Search algorithm, which ensures both the creation of the maze and the finding of solution path together with this, was utilized. It is made the information hide inside the pixels on the image, corresponding to the coordinates of the solution path obtained from the maze. The Lowest Bit Insertion method was used to hide information. In order to make the proposed method more robust, the data, which will be hidden before the data hiding process was encrypted with the AES encryption algorithm. This makes it difficult for third parties to obtain confidential data. The proposed method was tested with detailed security analysis and it was observed that data hiding / data extraction processes were successful.

Learning Mathematics in Metacognitively Oriented ICT-Based Learning Environments: A Systematic Review of the Literature

This article encompasses a systematic review of the research on ICT-based learning environments for metacognitively oriented K-12 mathematics education. This review begins with a brief overview of the research on metacognition and mathematics education and on ICT and mathematics education. Based on a systematic screening of the databases Web of Science and ERIC wherein three elements—ICT-based learning environments, metacognitive pedagogies, and mathematics—are combined, 22 articles/studies were retrieved, situated at various educational levels (kindergarten, elementary school, and secondary school). This review revealed a variety of studies, particularly intervention studies, situated in elementary and secondary schools. Most studies involved drill-and-practice software, intelligent tutoring systems, serious games, multimedia environments, and computer-supported collaborative learning environments, with metacognitive pedagogies either integrated into the ICT software itself or provided externally by the teacher, mainly for arithmetic or algebraic word problem-solving but also related to other mathematical topics. All studies reported positive effects on mathematical and/or metacognitive learning outcomes. This review ends with a discussion of issues for further theoretical reflection and empirical research.

MULTIMEDIA ENVIROMENT OF GERMAN POLEMIC DISCOURSE

This article is devoted to the study of the multimedia environment of the polemic discourse in German media with its diverse formats of impact on the audience and the actively developing internal dynamics of texts. If at the end of the XXth century the specifics of German media were the use of the Internet site as one of the possibilities to present copies of newspapers and magazines in electronic form, today we can speak of modified, hybrid Internet versions of printed publications that do not just create websites on the Internet that duplicate their main activity, but also combines the features of the traditional press and features of the functioning of texts on the Internet. The transition from linear, monomedia broadcasting platforms to discrete, multimedia ones has a significant impact on the process of creating, designing and placing modern polemics. Texts of articles and user comments are considered in the article as tmaterialization of the polemic discourse in the media. Polemic texts are formed on the basis of intertextual structures and have a hypertext nature. The use of multimedia tools (a variety of fonts, graphics, animation, photo, video and sound) in the text of the article allows the author not only to expand the amount of information provided, but also to qualitatively supplement its content through inline inclusions tn the text, to express the meaning of information by referring to verbal and non-verbal means; to provide a visual and figurative presentation of information (graphs, charts, tables), to attract attention and influence the audience, as well as to provide readers with the opportunity to participate in information exchange.

Extended environmental multimedia modeling system assessing the risk carried by pollutants in interacted air-unsaturated-groundwater zones

Simulation of the transport of hazardous pollutants in a variety of media is a challenge. In this paper, a novel Extended Environment Multimedia Modeling and Analysis System (EEMMS) for migration of pollutants from landfill through unsaturated site to groundwater is presented. The developed EEMMS consists of four pathways modules: air, landfill, unsaturated zone and groundwater zone. The finite element method in EEMMS framework is used to analyze these four pathways and the results are compared to the finite difference model and analytical model. The effectiveness of EEMMS has been verified through a case study of Trail Road Landfill site. The simulation of uncertainty was conducted with a quantitative technique of Monte Carlo Method. The Risk Quotient (RQ) results show that the low-risk area covers 10,000 square meters, where the predicted concentrations of benzene are between 1 and 1.2 μg L−1. However, the high-risk area covers almost 200,000 square meters. Contrary to FEM, the majority of the FDM and analytical predictions were too high and fell outside the high boundary of the experimental result. The EEMMS is a unique risk assessment tool that can be used for impacts on water resource quality, biodiversity, fate of pollutants in ecosystem, climate change, etc.

Feature mining simulation of video image information in multimedia learning environment based on BOW algorithm

With the development of computer image processing technology, video image information feature mining in multimedia environment has become a research hotspot in the field of education with its unique characteristics. However, the current method is to classify and retrieve through the video image information features. When the video image information is disordered, the multimedia video image information features cannot be classified, and the criterion for measuring the size of the video image information cannot be given, and the information feature mining accuracy is low. Therefore, this paper proposes a new efficient algorithm for multimedia video image information retrieval. Firstly, the SIFT features of the video image are analysed to obtain the SIFT features of the video image. Secondly, the SIFT feature is used for feature matching to identify the target image. Finally, the BOW algorithm is introduced to index the matched SIFT features, and the bag-of-words model, TF-IDF weighting and Euclidean distance are used to complete the similarity calculation of the image, and the feature mining of multimedia video image information is completed. The simulation results show that the proposed method effectively improves the feature mining speed and feature mining accuracy and has better robustness.

Online Computer-Based Clinical Simulations: The Role of Visualizations

BackgroundOne of the great promises of computer technology for education is the ability to combine text, sound, and visualizations to create multimedia-based simulations. Therefore, an understanding of whether and how to implement the variety of multimedia technology in nursing education is fundamental. MethodThis study compares the effectiveness of online computer-based simulations designed using three alternative multimedia approaches—video, animation, and agent-based visualizations—on learning of clinical reasoning skills. Participants in this study were undergraduate nursing students (n = 97). ResultsLearning gains were significantly higher for simulation that incorporated exploration of agent-based visualizations than for video- and animation-based visualizations. Interestingly, low achievers made significantly higher learning gains after learning with agent-based simulation than high academic achievers. Conclusion(s)This study proposes that visualizations play an important role in the effectiveness of learning with computer-based multimedia environments.

A regional spatial environmental multimedia modeling (RSEMM) approach for assessing the risk of antibiotics in river basin system – a China case study

In this paper, a regional spatial environmental multimedia modeling (RSEMM) approach is developed based on the integration of an environmental multimedia method (EMM) and a numerical water quality model. Emissions, inter-media mass transfer, physical transport and degradation processes are considered in the modeling system. The RSEMM approach is applied to the Beijing-Tianjin area in China, where there are many antibiotic emission sources throughout the Haihe River Basin including six streams. The antibiotic sulfadiazine (SDZ) is selected as the target contaminant in this basin region, including the urban area of Tianjin City. The predicted SDZ concentrations in the water and sediment zones align well with the reported monitoring data. A sensitivity analysis, using the Morris screening method, shows that flow rate and active sediment depth are the significant influential parameters for the regional water and sediment zones. Two modeling scenarios are further performed to assess health risks. They show that the SDZ concentrations and risks in the impacted environmental media could be reduced by possible mitigation actions. The RSEMM approach can also be applied to find the source-response relation in order to control other emerging contaminants in a complicated environmental multimedia site.

Mental Model Development in Multimedia Learning: Interrelated Effects of Emotions and Self-Monitoring

Learners’ emotions and metacognitive self-monitoring play a crucial role in mental model development, particularly in the context of multimedia learning. However, learning-centered emotions and self-monitoring have been investigated largely without accounting for their dynamic interrelations. In this study, the effects of both learner-state variables on mental model development were investigated, by modeling their interrelations over time during a multimedia learning episode. For this, 108 undergraduate students (Mage = 22.79, SDage = 3.42) were engaged in a multimedia learning environment to learn practical money skills. Learning-centered emotions of enjoyment, boredom, and frustration were repeatedly collected using self-reports. Learners’ self-monitoring was assessed using behavioral data in terms of time spent on accessing specific information in the multimedia environment. Mental model development was operationalized by assessing learners’ mental model accuracy (MMA) in pre- and post-tests, by using assessments of structural knowledge. Regarding the dynamic interrelations, panel models with the repeated measures revealed positive direct and indirect paths from earlier stages of self-monitoring to later stages of enjoyment. Conversely, negative direct and indirect paths emerged from earlier stages of boredom and frustration to later stages of self-monitoring. Regarding the effects of all variables on mental model development, a path model analysis with aggregated values revealed that enjoyment was unrelated to post-test MMA, whereas boredom negatively predicted post-test MMA. Additionally, frustration negatively predicted self-monitoring, which positively predicted post-test MMA. Finally, pre-test MMA was a negative predictor of boredom and positively predicted post-test MMA. The results demonstrate that the dynamic interrelations between different learning-centered emotions and self-monitoring can diverge in multimedia learning. In addition, this study provides insights into the joint effects and the relative importance of emotions and self-monitoring for mental model development in multimedia learning.
